Understanding BMW's Condition-Based Service (CBS)

The 2010 BMW Z4 sDrive35i utilizes BMW's Condition Based Service (CBS) system instead of a conventional fixed-interval maintenance schedule . Sensors and special algorithms take into account the different driving conditions of your BMW—including your driving style, distances traveled, and engine operating parameters—to determine current and future service requirements . This allows the maintenance regimen to be tailored to your individual usage profile, ensuring service is performed only when genuinely needed.

On the Control Display, you can view the remaining distances or times for selected maintenance tasks such as engine oil, brake pads, brake fluid, and vehicle checks . A service interval warning is standard equipment .

Critical Note: Service data is continuously stored in your vehicle's remote control. Your BMW Service Advisor can read out this data and propose an optimized maintenance approach . If the vehicle battery has been disconnected for storage periods, have a service center verify time-dependent maintenance procedures such as brake fluid and engine oil changes.
